I did consult a homeopath in the 90ies and early 2000nds, mostly because my mother was all super-pushy about it and I wanted her to quit pestering me. He would question me on the phone for 40 to 60 minutes. His anamnesis was the best I ever had. I don't recall if I even opened the package that came a week or so later containing the "LM Potence" of some obscure Homeopathic substance, i.e. a water and alcohol mixture in a small important looking flask. But I do remember being way calmer and way more educated on my condition. I thought I had heart problems and he pin-pointed reflux after the extensive questionaire and talk on the phone.
I've never spoken to an doctor for that long and I'd be suprised if any doctor had time or could afford such a thing. I would like to have such a medical expert to talk to that does not push obscure 'treatment' on me, that would be optimal.
I treated my reflux with healing-earth, baking soda, meditation/relaxation excercise and a change in diet and told my MD who wanted to sell me a "heart and lung condition" diagnosed in the record time of 2.5 minutes to fuck off. Never had problems since.
The point is: Good Homeopaths are actually quite well medically educated and can be terrific "anameticists" (wording?), because their main job actually is to talk to the patient, find out what's bugging him and - ideally - do a solid diagnose. That they only prescribe sugar-pills is a minor nuiscance from that perspective.
If astrology would lead to a new occupation in which the main purpose is talking to the patient and find out what exactly the condition is, it could be a good thing. Wether the professional in question would be a homeopath, an astrologer, magician or whatnot wouldn't really matter. Only treatment then, of course, would need to be decided upon by a different party.
Modern medicine need a profession specifically for anamnesis. Until that happens, homeopaths and perhaps even astrologers will fill that gap. Poorly at time perhaps, but they'll fill it.
